PURPOSE In this study, we examined whether additional, delayed regional FDG PET scans could increase the accuracy of the lymph node staging of NSCLC patients. MATERIALS AND METHODS Among 87 patients who underwent open thoracotomy or mediastinoscopic biopsy under the suspicion of NSCLC, 35 (32 NSCLC and 3 infectious diseases) who had visible lymph nodes on both preoperative whole body scan and...

BACKGROUND 18-Fluoro-2-deoxy-D-glucose positron emission tomography combined with computed tomography ((18)F-FDG PET/CT) scan is useful for diagnosis of osteoarticular infections. Whether (18)F-FDG PET/CT scanning may be used for therapeutic monitoring is not clear. The objective of this study was to develop (18)F-FDG PET/CT scanning for monitoring therapeutic response to antimicrobials in expe...

⁹⁰Y PET/CT can be acquired after ⁹⁰Y-microsphere selective radiation internal therapy (SIRT) to describe radioactivity distribution. We performed dosimetry using ⁹⁰Y-microsphere PET/CT data to evaluate treatment efficacy and appropriateness of activity planning from (99m)Tc-MAA scan and SPECT/CT. Twenty-three patients with liver malignancy were included in the study. (99m)Tc-MAA was injected du...

Venous thromboembolism (VTE) can be the first clinical manifestation of an occult malignancy. We aimed to assess the value, in daily practice, of positron emission tomography combined with computed tomography (PET-CT) for occult malignancy diagnosis in patients with unprovoked VTE.All PET-CTs performed over 5-years period (from January 2009 to October 2013) in adult patients followed in the Dep...

UNLABELLED To evaluate myocardial blood flow (MBF) and cardiac function with a single dose of (13)NH(3), electrocardiographically (ECG) gated PET acquisition was performed after a dynamic PET scan was obtained. Gated blood-pool (GBP) imaging with C(15)O PET was also performed to compare the left ventricular ejection fraction (LVEF) obtained using the 2 methods. METHODS Six healthy volunteers ...

Gated (4D) PET/CT has the potential to greatly improve the accuracy of radiotherapy at treatment sites where internal organ motion is significant. However, the best methodology for applying 4D-PET/CT to target definition is not currently well established. With the goal of better understanding how to best apply 4D information to radiotherapy, initial studies were performed to investigate the eff...

Samenvatting Het doel van deze studie was te onderzoeken of de bevindingen op een 18 F‑DCFPyL PET/CT-scan leiden tot verandering het behandeladvies voor patiënten met biochemisch recidief (BCR) prostaatkanker. 253 BCR-prostaatkanker bij wie werd gemaakt ter herstadiëring, werden geïncludeerd. Twee urologen formuleerden voorgestelde behandeling elke patiënt voor- en nadat zij kennis hadden genom...

To evaluate myocardial blood flow (MBF) and cardiac function with a single dose of NH3, electrocardiographically (ECG) gated PET acquisition was performed after a dynamic PET scan was obtained. Gated blood-pool (GBP) imaging with C15O PET was also performed to compare the left ventricular ejection fraction (LVEF) obtained using the 2 methods. Methods: Six healthy volunteers and 34 patients with...
